Imprimir pàgines man



Hola,

potser és molt obvi, però estic intentar imprimir una pàgina del man, o sigui 
poder passar-la a ps o html i sempre em trobo amb un error. Em podeu donar un 
cop de mà, si us plau.

Exemple:
palomo@lira:~$ man --help
usage: man [-c|-f|-k|-w|-tZT device] [-adlhu7V] [-Mpath] [-Ppager] [-Slist]
           [-msystem] [-pstring] [-Llocale] [-eextension] [section] page ...
...
-H, --html                  use lynx or argument to display html output.
....
palomo@lira:~$ man -H ls > ls.html
Reformatting ls(1), please wait...
/usr/bin/groff: can't find `DESC' file
/usr/bin/groff:fatal error: invalid device `html'
man: command exited with status 768: /usr/bin/zsoelim /tmp/zmanawQAPb | 
/usr/bin/groff -mandoc -Thtml > /tmp/hmanwxSmCe/ls.html
palomo@lira:~$

També si faig: man man

....
   man -l -Tdvi ./foo.1x.gz > ./foo.1x.dvi
           This  command  will decompress and format the nroff source manual 
page ./foo.1x.gz into a device independent (dvi) file.  The redirection  is 
necessary  as  the -T flag causes output to be directed to stdout with       
no pager.  The output could be viewed with a program such as  xdvi  or         
further processed into PostScript using a program such as dvips.

......

aleshores:

palomo@lira:~$ man -l -Tdvi /usr/share/man/man1/ls.1.gz > ./ls.dvi
/usr/bin/groff: can't find `DESC' file
/usr/bin/groff:fatal error: invalid device `dvi'
man: command exited with status 768: /usr/bin/zsoelim /tmp/zmant2qVCo | 
/usr/bin/tbl | /usr/bin/groff -mandoc -Tdvi

Bé, que punyetes estic fent malament?

Gràcies per endavant.

Leo
